What do these two changes have in common? adding dish soap to water in a sink carving a piece of wood Select all that apply. Both are only physical changes. Both are chemical changes. Both are caused by heating. Both are caused by cooling.

## Step 1<br />The problem asks us to identify the commonality between two changes: adding dish soap to water in a sink and carving a piece of wood. <br /><br />## Step 2<br />The first change, adding dish soap to water in a sink, is a physical change. This is because the soap molecules are simply dispersed throughout the water, but no new substances are formed.<br /><br />## Step 3<br />The second change, carving a piece of wood, is also a physical change. This is because the wood is being physically altered (shaped), but no new substances are formed.<br /><br />## Step 4<br />Therefore, the commonality between these two changes is that both are physical changes.
